Influence of phosphorus fertilization and lime in the grass forage ecophysiology

Abstract

The objective was to search studies that showed the influence of phosphorus fertilization and limestone on the ecophysiology of forage plants. Phosphorus is an essential element for plant physiology participating in the process of obtaining energy. However it is common deficiency of this element in the soil, thus fertilizing with this element is extensively tested. The magnitude of the response varies with the type of plant, soil, interrelation with other nutrients, however response observed growing as it increases the dosage of phosphorus, there is increase in the density of tillers, increased mass roots, increasing the phosphorus content in the leaves. Already acidity is the most discussed issue in tropical soils being the most used product in lime is limestone and response to liming can be positive, negative, depending on other factors. Mobility in soil calcium and phosphorus is low, so the response of the plant is susceptible to the influence of other factors such as the availability of other nutrients.
